Ah, I see the use case now-where you get it replaced by a 3rd party or buy a stolen phone, do you want it bricked by a software update? I don't know. I don't know that I care much about that use case TBH.

What I don't want is this: someone steals my phone and then replaces the fingerprint sensor and has access to everything, including the ability to reset and resell the phone.

That’s not possible anyway because the phone can detect and reject the replacement sensor. If it couldn’t then how would it know to brick itself? Instead it should just fall back to PIN authentication, which is actually more secure and how it worked before the update
